Application flied June 11, 19%. ScrialNo. $87,918,

To all whom it may concern:

Be it known that I, WILnUR T. NORTON, a citizen of the United States, residin I at Alton, county of Madison, and State of lllinois, have invented an 1m rox'ement in Cultivators, oi which the to owing description, in connection with the accompanying drawing, is a specification, like numerals on thedrawingrrepresenting like parts.

his invention relates to cultivators and has for its object to provide a novel form of cultivator which may be used either to cultisoi.

- the oultigrat'or fihowi. the

thereo vate and stir up the soil to a considerable depth or may be used simply for cutting the Weeds immediately below'or above the surface of the soil. These objects are accomplished by makin the cultivator with two or more elon ate cultivator blades which are supports sothat the angular position relative tov the horizontal may be changed. When the cultiwator blades are situated at a considerable inclination, they operate to cut into the soil and'stir the latter up to a considerable depth and they also operate to force or crowd the soil laterally so that the cultizator thus arran ed can be used for billing up pul' oses as well as for cultivating purposes. W on the cultivator blades are arranged very nearly on a horizontal plane,

they do not cut into the soil to any'great depth, but act merely to cut the weeds sli htly below or above the surface of the The device can thus bewused either as a weed cutter-or as a cultivator.

In the accompanying drawings wherein is. shown the referred embodiment of my invention for tie urpose of illustrating the principle thereof, i re I is a top plan view of a cultivator sin .odyin thein' 'ention;

This on tivator frame carries two cultivator blades 10 and 11 which preferably extend substantially the full length of the cultivator frame. lhese blades are pivoted to, the cultivator frame so that theyhma Y be swung from an approximately horizontal pothe character of the work desired to be accomplished by the cultivator. It is within my invention to pivotally support these blades on the frame in any suitable way. One convenient way of accomplishing this obiectis by making the frame with a plurality of-depending supports 12 to which the inner ed es. of the cultivator blades are iv-' o ted. '1' 1e supports shown are rovide at their lower ends with e es 13 w ich are re ceived in notches 14 ormed in the inner edges of the blades, and the eyes receive within them pivotal pins 15 carried by the Medea-these pins forming the pivotal points about which the blades turn.

The blades may be adjusted and held in the desired position in a variety of Ways without departing from the invention. T e drawing shows admsting screws l6 carriedby the sills '3. and 4 which screws are p voted at of ass ssment .lgiiesserew. Ea

vator blades are thrown into the inclined position shown in Fig. 4 or in some other inclined position, w ile when the adjusting screws are lowered, the cultivator blades are thrown into an approximately horizontal position, as shown in Fig. 3.

When the cultivator blades are set at an inclination, such as shown in Fi 4, the 1 cut up and stir up the soil to a consi erable depth and by setting them at a still greater inclination, they wil operate to force the soil laterally and can thus be used for billing-up purposes.

By adjusting the cultivator blades into the approximately horizontal position as shown in Fig. 3, they will not stir up the soil to any depth but will slice under the top surface of the soil and thus operate to cut any weeds which may be rowing. When adjusted in this way the on tivator has the function of a weed cutter.

ometimes it is desirable to cut the weeds above the ground instead of below the ground, and this can be acoom lished with my improvement by merely a justing the cultivator blades so that .the cutting edges thereof tilt upwardly slightly. When thus adjusted they ride over the surface of the ground and will cut the weeds entirely above the ground.

At the front end of the frame I have shown 8. depending stud or 0st 30 which carries at its lower end a plows are or shovel 31 having any suitable or usual shape. 32 designates a clevis or other connection to which the draft apparatus may be attached. 33 designate the usual handles rising from the frame.

The cultivator blades 10 11 are preferably made detachable from the frame so that they can be readily removed whenever it is de sired to sharpen them or to repair or otherwise fix them. One convenient way of making them thus removable is by making the ivotal pins 15 of less length than the note cs 14, so that by moving the blades forwardly the pivotal pins may be disengaged from the eyes 13. After this is done the check-nutsZO may be removed thus permitting the adjusting screw 16 to be withdrawn from the arm 19. I prefer to make the edge 34 of the blades serrated, as shown best in Fi 1, as an edge of this construction is more e ective in breaking up the soil and is also more effective in cutting Weeds.

A cultivator embodying my invention is provided with a cultivator blade which extends longitudinally of the frame and the effective height of which can be varied. In one embodiment of my invention this is secured by pivotall mounting the cultivator blades as above. escribed. I'may also secure this effect by em loyin'g additional blades or "ridgers as I have termed them,

act as additional means for billing-up puroses. One advantage of using these ridgers is that they can be employed in an position of the cultivator blades.

A cultivator embodying my invention is much easier of draft than an ordinary tooth or shovel cultivator because while an ordinary shovel cultivator has five or seven shovels, my cultivator em loys but a single shovel at the a ex and t e blades are arra ed so that tiiby slide through the ground wit a minimum of resistance of friction. Further because of the triangular sha e of the cultivator absolutely complete cu tivation of the soil is insured for a width equal to that between the rear ends of the frame.

Havin fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

1. In a cultivator, the combination with a cultivator frame, of two divergently-arranged cultivator blades extending longitudinally thereof, each blade being pivoted to the frame to turn about a horizontal axis extending longitudinally of and parallel to said blade.

2. In a cultivator, the combination with a cultivator frame, of two divergently-arranged cultivator blades extending longitudinally thereof, each blade being pivoted to the frame to turn about an axis parallel to said blade, and adjust' blade into different ang es to the horizontal.

3. In a cultivator, the combination with a frame comprising two side sills, each having a post depending therefrom, of cultivator blades ivoted to said osts, and means adjust t e angular position of said blades.

4. In a cultivator, the combination with a frame, of two divrgently-arranged cultivator blades extending longitudinally thereof, and a vertically-adjustable ridger associated with each cultivator blade.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesse.
